DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package data conversion apparatus for creating data for controlling various NC processing apparatuses based on structural design data of a package (container) created by a package CAD system or the like. is there.

[0002]

2. Description of the Related Art For example, in the manufacture of packages (containers) such as paper containers and cardboards for packaging various commodities such as foods, various NC processing apparatuses (for example, a laser processing apparatus for forming a die, a plate). A lower plotter device, a face plate generating device, etc.) are used. Conventionally, these creating devices are:
The control is performed by control data for each processing apparatus created based on design drawings or structural design data by package CAD by an expert who has abundant package design experience.

[0003]

However, such a conventional manual data creation operation has various problems to be solved. That is, for example, in the case of forming a die by using a laser processing apparatus, it is preferable to make the moving distance of the laser cutter as short as possible in order to improve processing efficiency. Creating control data in consideration of efficiency imposes a heavy burden on a data creator, and is a factor in reducing the work efficiency of an operator. Further, the control data created due to differences in the abilities of the workers and the like are not all the same, and as a result, there is a possibility that the processing efficiency such as the quality of the final product package or the processing time varies.

In recent years, attempts have been made to input and use the structural design data of a package CAD system as it is to a machining apparatus. However, in a CAD system, design is usually performed in consideration of only the efficiency at the time of design. Therefore, the structural design data output from the CAD system has not been subjected to the processing for improving the processing efficiency at the time of processing, and thus there is a problem that the efficiency at the time of processing is not necessarily improved.

At the stage when the structural design data is completed, a prototype of the package is actually manufactured and the package is checked. At this stage, the structure design is performed without using a die for mass production. The package paper is directly cut by a laser processing device, a plotter cutter, or the like that operates based on the data. At this time, the laser processing device etc. does not cut out the paper at once like cutting die, but cuts out sequentially along the outer shape of the package, so if the package has cutout parts such as windows, Depending on the order of cutting the paper, the package may be cut out first, and then the window or the like of the package may be cut out. In such a case, the fixing of the sheet becomes uncertain, and the accuracy of cutting the sheet of the package is reduced due to vibration, displacement, distortion, and the like of the sheet in the package portion. In particular, with a plotter cutter in which the blade directly contacts the paper, the possibility that the paper is shifted or distorted was high.

The present invention has been made in view of the above circumstances, and can convert structural design data output from a package CAD system into data in which the processing efficiency of a processing apparatus including a prototype plotter cutter is optimized. It is intended to provide a package data conversion device.

[0007]

The above-mentioned "means for solving the problem"
In the section "Operation", the present invention has been described with reference numerals shown in FIG. 1, but it is needless to say that the present invention is not limited to the configuration shown in FIG.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic diagram showing a package data conversion device according to one embodiment of the present invention. As shown in FIG. 1, the package data conversion device includes an input unit 1 including an interactive input device such as a keyboard and a data reading device such as a magnetic disk device and an online device; a display device 2 including a display device; It is mainly composed of an arithmetic unit 3 including a personal computer (CPU), a storage unit 4 including a magnetic disk device and a memory device, and an output unit 5 including a magnetic disk device and an online device.

The input means 1 receives structural design data from a package CAD system or the like. The structural design data input via the input means 1 is stored in the storage means 4 via the calculation means 3 and displayed on the screen by the display means 2. The display means 2 is connected to the arithmetic means 3 and displays the structural design data input by the input means 1 on its screen, and displays the result of the arithmetic processing by the arithmetic means 3 as needed.

The calculating means 3 extracts reference data from the data constituting the outer shape of the package in the expanded state, out of the structural design data input by the input means 1, and uses the reference data as connection source data to extract the reference data. It has a function of searching the structural design data for data having an end point that coincides with the end point of the data, and sequentially connecting the searched data to the connection source data to create a data unit.

The calculating means 3 arbitrarily extracts connection source data from the structural design data excluding the data unit having the reference data, and converts the data having an end point whose end point coincides with the connection source data. It has a function of searching from structural design data and sequentially linking the searched data to the connection source data to create a data unit.

Further, the arithmetic means 3 sets a data unit including the reference data among the created data units as a reference data unit and extracts it as connection source data, and extracts the data unit closest to this reference data unit on a coordinate axis. It has a function of searching for units, sequentially connecting the searched data units, and constructing one combined data unit.

The storage means 4 is connected to the arithmetic means 3 and temporarily stores the structural design data input by the input means 1 and temporarily stores the data processed by the arithmetic means 3. The output means 5 is also connected to the arithmetic means 3, and outputs the composite data unit created by the arithmetic means 3 as new structural design data.

Next, the operation of the package data converter of the present invention will be described with reference to the flowcharts shown in FIGS. 3 and 4 and FIGS. 5 to 7. (1) Input of Structural Design Data First, the structural design data of a package having coordinate values in a rectangular coordinate system on a specific plane obtained by a package CAD or the like using the magnetic disk device / on-line device or the like among the input means 1 is input. It is input (step SP1). As shown in FIG. 5, the structural design data in the present embodiment is input as units (surfaces) 10... Constituting the package, and the data is represented by an outline of a development view (blank view) of the package. It is composed of outer shape data 11 to be constituted and bent line data 13 which is a connecting portion of the panel. Note that the outline here refers to a line type to be cut when processing a sheet with a laser processing machine or the like. Further, as shown in FIG. 7, there is a portion to be cut such as a cutout portion 12 in the panel or across several panels, and this is also treated as an outline.

The outline data 11 and the bending line data 13 are further composed of straight line and curve data. Therefore, the data input to the apparatus of this embodiment is divided into straight lines and curves, and both end points 14 and 14 (FIG. 5) of these straight lines and curves.
XY coordinate value data of which is partially enclosed by a circle. One of the end points 14 and 14 in these data is N
The end point is processed by the C processing apparatus as the starting point of the processing operation, and in that sense, each data has directivity.

The data input by the input means 1 is temporarily stored in the storage means 4 via the operation means 3. The following processing is performed for each line type of the structural design data constituting the package, and the processing order is such that the bending line is processed first and the outline is performed last. Further, differences between the respective processes will be described as appropriate, but the other points are completely the same.

(2) Extraction of reference data The calculating means 3 outputs, when the processing line type is the outline data 11 in the structural design data input by the input means 1,
Data having the maximum X coordinate value is extracted as reference data as shown by the line segment 20 in FIG. 5 (step SP2). The extracted reference data is the first connection source data.
In this embodiment, the reference data is extracted with reference to the maximum value of the X coordinate of the data.
For example, data having the minimum coordinate value may be extracted or the Y coordinate value may be referred to as long as the data constitute the cutout portion 12 shown in FIG. That is,
It is necessary not to extract the outline data 11 inside the outer periphery of the package as the reference data like the cutout portion 12 shown in FIG.

The extracted reference data is stored by the storage means. When the processing line type is other than the outline, the reference data is not extracted, and arbitrary data is extracted as the connection source data, and the extraction conditions of the connection source data are not particularly limited.

(3) Creation of Data Unit Next, the calculating means 3 calculates the end point coordinates 2 which coincide with the coordinates of one end of the reference data or other connection source data.
Data having 0a is retrieved from the structural design data (step SP3). In FIG. 5, a line segment 21 is data to be searched. Next, the calculation means 3 determines whether or not there is corresponding data as a result of the search (step SP4). If there is such data, the searched data is connected to the connection source data with matching direction (SP5). . The directionality of the data referred to here is two end points 1 of one piece of data.
If one of the four is the start point, the other is the end point, indicating that the direction has a direction from the start point to the end point as indicated by an arrow along the line segment 20 in FIG.

Next, the end point coordinates 21 of the linked data
search for data having an end point matching a (SP
3). This process is repeated until there is no continuous data. In other words, as shown by the line segment 24 in FIG. 5, one end point coordinate 24a of the data is not connected to the end point of the other data, for example, one end point of the data exists independently or the other end point exists. The connection of the data is terminated at the part connected to the line segment between the end points of the data.

In FIG. 5, the process is repeated until the data 24 is linked, and when there is no corresponding data, the above process (SP3 to Sp5) is repeatedly performed on the other end point coordinate 20b of the link source data. In FIG. 5, the data group connected through the series of processing, which is performed until the data 28 is connected, is registered in the storage unit 4 as a data unit (SP6).

Next, the calculating means 3 determines whether there is any data that has not been processed (step SP7), and if there is such data, the unprocessed data is used to determine the data to be the connection source data for connection. Optionally extracted (SP8). The extraction of the connection source data is not performed as in the extraction of the reference data, but is arbitrarily extracted from the remaining structural design data.

When the new connection source data is extracted,
The above-mentioned processing (SP3 to SP7) for searching for and connecting data continuous to the connection source data is performed to create a data unit, which is registered in the storage means. And calculating means 3
Repeats the processing from SP3 to SP8 until all the structural design data constitutes a data unit, and then proceeds to SP9.

(4) Linking of Data Units The calculating means 3 uses the data unit containing the reference data as a reference data unit from the data units registered in the storage means 4 and sets the connection source data unit U1
(Shown in FIG. 5) (SP9). Next, the arithmetic unit 3 searches for a data unit having an end point coordinate closest to the end point U1a of the extracted connection source data unit U1 on the coordinates (step SP10). In FIG. 6, the data unit U2 is searched. Next, as a result of the search, the calculating means 3 determines the presence or absence of a corresponding data unit (step SP11), and if there is a corresponding data unit, configures the searched data unit as a reference data unit U1. The connected data are linked in the same direction (SP12). further,
The data unit having the end point coordinates closest to the end point of the connected data unit is searched and connected, and thereafter the same processing is repeated until all the data units are connected (SP10 to SP12). When all the data units are linked and one combined data unit is created, this combined data unit is registered by the storage means, and the process proceeds to SP13.

(5) Output of Structural Design Data The calculating means 3 inverts the data configuration order of the registered composite data unit only when the processing line type is the outer shape line,
Conversion processing is performed so that the reference data unit including the reference data is the last data unit of the combined data unit, that is, the end on the end point side (SP13). The converted synthesized data unit is output as new structural design data by the magnetic disk device, the online device, or the like of the output unit 5 (SP14). According to the procedure described above, the structural design data of the package can be converted.

Here, in this embodiment, the reference data can be extracted from the data constituting the outer shape of the package by using the data having the largest X coordinate among the structural design data as the reference data. That is, the outline data 11 inside the package such as the cutout portion 12 shown in FIG. 7 is not extracted as the reference data. Then, the data unit including the reference data is set as the reference data unit, and the reference data unit is set as the connection source data unit. The data units are sequentially connected, and when outputting as one combined data unit, the order of the data units is changed. By inverting and outputting, the reference data unit can be the last data unit of the combined data unit.

Therefore, when the package is cut out from the package paper by the NC processing device such as the plotter cutter based on the composite data unit, that is, the structural design data output from the package data changing device, the reference data unit is used. The part will be cut out last. That is, after the data unit of the outer portion of the package is cut last and the package is separated, the cutout portion 12 and the like shown in FIG. The displacement and the like can be suppressed to a minimum, and the accuracy of the package can be improved.

Further, the package data conversion device
The output structural design data can also be used for the creation of a die using an NC processing device or the like. When cutting paper or creating a die, data with matching end points are connected in consideration of the directionality. In this way, the combined data unit is generated in such a manner that the integrated data units are connected in the order of the end points in consideration of the directionality of the integrated data units. The cutting and drawing operations by the NC processing device such as a plotter device are performed in a certain direction, and the processing efficiency is greatly improved. Further, this data conversion work is performed according to a certain rule, and a certain effect is obtained regardless of the skill of the operator, and there is no variation in the processing efficiency such as the quality of the final product package or the processing time. . The details of the package data conversion device of the present invention are not limited to the above embodiment, and various modifications are possible.
